Hardening

ThermTech refers to hardening as a process in which the entire alloy or components microstructure is being changed by a thermal process to show an overall increase in the parts mechanical properties which results in a higher hardness than the alloy or component originally had. This typically is done through quenching the parts in liquid or by aging them at an artificial temperature.

Marquench Hardening

ThermTech is proud to offer marquench hardening for machined parts. This process is usually used for higher alloy grades of steel that are prone to excessive distortion or cracking.

Oil Quenching

ThermTech is proud to offer oil quench hardening for steel castings. The process is typically employed on castings made from many low to medium- alloy steel grades with carbon in excess of .40%, or those with higher amounts of total alloy content.

Polymer Quenching

ThermTech is proud to offer polymer hardening of steel castings when a quench faster than standard oil quenching is required. Polymer quench hardening is typically employed on castings made from low to medium alloy steel grades and sometimes for higher alloy steels with heavy sections.

Water Quenching

It is optimum for forgings to receive proper water quench hardening in order to avoid undesirable microstructural components, which can lead to low hardnesses, mechanical properties, and failures during service.

Austempering

Between our neutral salt bath furnaces and our larger austempering furnaces we have the capabilities to provide austemper heat treating for a wide variety of machined components & stampings.

Age Hardening

Age hardening, also known as precipitation hardening is a low temperature heat treating process to increase the strength and mechanical properties of many aluminum alloys.
